BATTERYBattery: Safety

L90

80A

I -DANGER ACID

Sulphuric acid is a highly aggressive and toxic substan-

ce which corrodes most metals.

When handling batteries, it is very important to take the following precautions:

- protect your eyes by wearing goggles,

- wear acid proof gloves and clothing.

II - DANGER RISK OF EXPLOSION

When a battery is charging oxygen and hydrogen areproduced. Gas formation is at a maximum when thebattery is completely charged, and the quantity of gasproduced is proportional to the strength of the chargingcurrent.

The oxygen and hydrogen mix in the space on the sur-face of the plates, forming an explosive mixture. Thismixture is highly explosive.

The smallest of sparks or heat sources can cause anexplosion. The explosion is so strong that the batterycan shatter and spray the acid into the surrounding at-mosphere.

People nearby are at risk (exploded fragments, acidsplashes). Acid splashes are dangerous. They also da-mage clothing.

Safeguarding against the danger of explosion, whichcan be caused by handling a battery carelessly, mustbe taken very seriously.

IMPORTANT

- A battery contains sulphuric acid, a dangeroussubstance.

- When a battery is being charged, oxygen andhydrogen are created, the mixture of these gasescan presents a risk of explosion.

IMPORTANT

- If acid splashes on to your clothing, rinse all conta-minated areas thoroughly in water.

- If it comes into contact with skin, consult a doctor.

IMPORTANT

Check that all consumers are completely switchedoff.

When a battery is being charged in a room, switchoff the charger before connecting or disconnectingthe battery.

Do not place any metallic objects on the battery asthis may create a short circuit across the terminals.

never hold a naked flame, a welding gun, blowtorch,a cigarette or a lighted match near to a battery.

BATTERYBattery : Checking

L90

80A

I -CHECKING THE BATTERY

1 - Inspection of the mounting

Check that the battery is correctly secured (battery mounting bracket (1.2 daNm)):

- excessive tightening of the battery bracket is dan-gerous, the battery tray may be damaged or bro-ken,

- insufficient tightening of the battery mounting brac-ket leaves a clearance, the battery tray may beworn through the resulting friction or break from im-pact.

2 - Visual cleanliness check

Check that there is no creep leakage (sulphation) onthe battery terminals.

Clean the battery terminals.

Grease the battery terminals if necessary.

Check the tightening torque of the battery terminalnuts (0.65 daNm) on the terminals.

II - BATTERY CHARGE

The battery check is made using tool (Ele. 1593).

1 - Charger validation test reminder.

It is essential to use a constant voltage charger, toprevent heating proportional to the charge current.

2 - Test

Set the charge current setting potentiometer to maxi-mum.

Read off the voltage displayed on your charger or atthe battery terminals.

You must stop charging if the charger is not constantvoltage.

III - CHECKING PROCEDURE

(See NT 3682A, Battery, 80A, Battery Check).

IMPORTANT

- Poor contact may cause starting or chargingfaults, create sparks and cause the battery toexplode.

- If acid splashes on to your clothing, rinse allcontaminated areas thoroughly in water.

- If it comes into contact with the skin or eyes,seek medical attention.

WARNINGThese vehicles are equipped with an electrolyteconsumption battery. Topping up the electrolyte istherefore prohibited.

WARNING

If the voltage displayed is above 15 V, the chargeris not constant voltage (using it endangers thebattery).

IMMOBILISERGeneral information

L90

82AThe function of the engine immobiliser is ensured by akey recognition system with exchanges of encryptedcodes.

A coded chip (operating without a battery) independentof the remote control function is incorporated into thehead of each of the vehicle's keys.

When the ignition is switched on, the UCH exchangesinformation with the key head by a transponder ring onthe ignition switch.

If the UCH recognises the key code, it authorises theengine start and the injection is unlocked; the enginecan be started.

The engine immobiliser is activated a few seconds afterthe ignition is switched off (indicated by the red engineimmobiliser warning light flashing on the instrument pa-nel).

A factory preset code of twelve hexadecimal charactersis allocated to the vehicle to allow the engine immobili-ser system to be repaired.

This repair code is required in after sales in order to:

- add keys,

- replace one or more keys,

- deallocate one or more keys (e.g. if lost or stolen),

- replace a UCH.

Note:

For all key or UCH programming operations, therepair code number will be asked for by at DACIANetwork Techline (tel. 00 40 248500555) . In thiscase, it is necessary to provide the VIN and vehicleserial number.

82A-2

IMMOBILISERDescription

L90

82AWith this system, the engine immobiliser is activated afew seconds after the ignition is switched off (indicatedby the red engine immobiliser warning light flashing).

This systems consists of several components.

I -A KEY HEAD FITTED WITH ELECTRONICS

The key head fitted with electronics (1) allows the engi-ne immobiliser and central door locking to be comman-ded by radio frequency (depending on the version).

II - A TRANSPONDER RING

The transponder ring (2), located around the ignitionswitch, is fitted with an electronic device for transmittingthe key code to the UCH.

III - A UCH

The UCH (3) is located on the dashboard (see 87B,Connection unit, UCH).

107867

Note:

The immobiliser chip is now integrated in the remotecontrol printed circuit.

IMMOBILISERDescription

L90

82AFor the engine immobiliser function, the UCH carries out the following functions:

- decodes the key signal,

- communicates with the injection computer,

- controls the instrument panel red warning light, com-municates with the diagnostic tool.

IV - AN ENGINE IMMOBILISER RED WARNING LIGHT

The engine immobiliser red warning light located on the instrument panel used signals:

- the activation of the engine immobiliser system (oneflash per second),

- the non-recognition of the key (rapid flashing),

- a system failure (rapid flashing),

- programming of a key.

82A-4

IMMOBILISEROperation

L90

82AWhen the engine immobiliser system is operational, theengine immobiliser red warning light flashes (slowflashing: one flash per second).

When the ignition is switched on, a process of mutualrecognition between the key and the UCH begins.

If the key presented and the UCH have recognisedeach other, the UCH sends an unlocking code by wireto the injection.

If the injection recognises the code, it unlocks andauthorises the engine start.

SPECIAL CASES:

The injection computer is supplied uncoded. It has tobe programmed with the engine immobiliser code whenit is installed, to allow the vehicle to be started.

Switch on the ignition for a few seconds without startingthe engine. Switch the ignition off; the immobiliser func-tion will be activated after a few seconds, (the red im-mobiliser warning light will flash).

If the key and UCH codes do not recognise each other,the system remains locked. The engine immobiliser redindicator light flashes (quickly).

The engine is authorised to start by default for 2 se-conds only.

WARNING

When the vehicle battery has a low charge, the dropin voltage caused by a starter request could reacti-vate the immobiliser. If the voltage is too low, theengine cannot be started, even by pushing the vehi-cle.

83A4 - Trip computer (ADAC)

The various sequences of the trip may be displayedinstead of the mileometers by pressing the button onthe end of the windscreen wiper stalk (« ADAC » but-ton).

It is reset by pressing button (1).

The trip computer information is displayed on screenfrom the trip meter as follows:

5 - Fuel consumed (F)

(Since the last reset).

Maximum capacity: 999 L

6 - Average consumption (H)

(in l/60 miles (100 km) since the last reset).

This is only displayed after the vehicle has travelled400 m.

This takes into consideration the distance travelled andthe fuel consumption since the last reset.

7 - Current fuel consumption (A)

(In l/60 miles (100 km)).

This is only displayed when the vehicle speed exceeds18 mph (25 km/h) .

This value should not exceed 29.9 l/60 miles (100 km).

If there is no flow pulse for at least 1 s and if the speedis above 18 mph (25 km/h), the display is0 l/100.

8 - Estimated range with remaining fuel (C)


This is the potential range, obtained by taking into ac-count the distance travelled, the amount of remainingfuel in the tank and the fuel consumed.

Maximum capacity: 6210 miles (9999 km)

9 - Distance travelled (E)


Maximum distance: 6210 miles (9999 km)

10 - Average speed (G)



This is obtained by dividing the distance travelled bythe time elapsed since the last reset.

The time base is inside the trip computer.

IV - FAULT FINDING

1 - Fault detection

The trip computer has searched to detect the faultswhich may affect the indications supplied by the displayor by the indicators.

If the following indicators:

- fuel consumed,

- fuel range,

- average consumption,

- current consumption,

Are replaced by flashing arrows, this indicates a conti-nuous flow signal fault for over 10 miles (16 km).

If only the fuel range indicator is replaced by flashing ar-rows and the minimum fuel level warning light is lit, thisindicates a sender unit fault for over 100 s

If the fault disappears, the minimum fuel level warninglight goes out and the fuel indicator segments are lit(except if the fuel is it minimum level)

In addition to indicating the fault by the display flashingor with a receiver segment fault, the trip computer sto-res the fault in non-volatile memory.

In all cases, proceed to the fault finding sequence todisplay the sensor fault memory.

108991

E F

G H

83A-17


L90

83AThe trip computer includes a test program (fault finding sequence):

- for the different segments of the display,

- for the sensors used (fuel gauge, flow signal).

2 - Fault finding sequence

To access the fault finding sequence, press and holdthe « ADAC » button on the end of the windscreen wi-per, with the ignition on but the engine off.

Throughout the fault finding sequence, the speedome-ter needle sweeps its dial at the following speeds 6mph (10 km/h), 30 mph (50 km/h), 55 mph (90 km/h),80 mph (130 km/h), 105 mph (170 km/h).

In the same way and at the same time, the enginespeed indicator needle sweeps its dial at speeds of1000, 2000, 3000, 4000, 5000, 6000, 7000 rpm.

These two sweeps are performed periodically alterna-tely every second in an outward direction and then in aninward direction.

The software versions appears (I).

The LCD test appears (L)

All the segments on the LCD display should be lit.

To proceed to the next test, press button (1).

The test quantity of fuel remaining in the tank appears(K).

The value displayed should correspond to the quantityof fuel remaining the tank in litres.

To proceed to the next test, press button (1).

The fuel flow test in litres/hour appears (engine run-ning) (J) (version « ADAC »).

The value should be displayed with the engine is run-ning.

To go onto the next test, press button (1).

3 - Viewing stored faults.

a - Fuel tank sender unit fault

If a fuel sender unit fault appears two messages may appear after 100 s :

- « Jo » for an open circuit on the fuel tank sender unit ,

- « Jc » for a short circuit on the tank sender unit.

b - Fuel flow fault

If a fuel flow fault appears the message « d » may bedisplayed.

« to » for an open circuit on the coolant temperaturesensor.

« tc » for a short circuit to earth on the coolant tempe-rature sensor.

4 - Reinitialising the system and exiting the fault finding sequence

To exit fault finding mode, press button (1). This clearsall of the stored faults and resets the trip computer se-quences.

To exit the fault finding sequence without clearing thestored faults, just switch off the ignition.

CONTROLS - SIGNALSHeated rear screen: Repair

L90

84AThe screen printed heated grid on the inner face of thewindow may have an accidental cut, making the affec-ted part of the circuit useless.

Determine the exact location of the cut using a volt-meter.

Faults such as these can be repaired by using theheated rear screen repair varnish available at the-magasin Pièce de rechange.

I -DETERMINING THE EXACT LOCATION OF THE CUT USING A VOLTMETER

Switch on the ignition.

Switch on the heated rear screen supply.

1 - Detection between lines B and A

Connect the + wire of the voltmeter to the + supplyterminal of the rear screen.

Put the voltmeter - wire on a filament at the - terminalend of the rear screen (line B); the voltage obtainedshould be roughly equal to the battery's.

Move the - wire to line A (arrow): the voltage gradual-ly drops.

A sudden voltage drop indicates that the filament iscut at that point (carry out this operation for each fi-lament).

2 - Detection between lines C and A

Connect the - wire of the voltmeter to the - terminalof the rear screen.

Put the voltmeter + wire on the filament at the + ter-minal end of the rear screen (line C); the voltage ob-tained should be roughly equal to the battery's.

Move the + wire towards line A (arrow); the voltagegradually drops.

A sudden voltage drop indicates that the filament iscut at that point (carry out this operation for each fi-lament).

II - REPAIRING THE FILAMENT

Clean the section to be treated locally to remove alldust or grease, preferably using alcohol or a glasscleaner, and wipe with a clean, dry cloth.

To ensure that the new line is straight, before var-nishing, apply adhesive tape to either side of the sec-tion to be repaired, leaving the conducting line free.

Before using the varnish, shake the bottle to preventthe silver particles settling on the bottom.

Repair

Carry out the repair using a small brush, applying asufficiently thick layer. If applying successive coa-tings, allow sufficient drying time between each coa-ting and do not repeat the operation more than threetimes.

If the varnish runs however, it can be removed usinga knife point, but only after several hours, once theproduct has properly hardened.

The adhesive tape used as a guide must not be re-moved until around one hour after application. Thetape must be pulled off perpendicularly to the resis-tance, in the direction of the arrow.. When used at anambient temperature of 20˚C, the varnish is fully dryin three hours. At lower temperatures the drying timeis slightly longer.
